Dust collector chip separation baffle

Abstract

A dust collector for collecting sawdust and wood chips during use of wood working tools includes a conduit or hose connected through an impeller forcing air with entrained dust and chips to an inlet ring of a single stage dust collector. A particle collector reservoir is connected on the bottom of the inlet ring and a filter element is connected on top of the inlet ring. A tapered ring wall with a central opening is provided in the inlet ring and a baffle is mounted in the central opening of the ring wall. The baffle is of a cone shape and tapers an opposite direction from the frusto-conical ring wall. The inlet opening of the inlet ring is directed to between the ring wall and the baffle.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates generally to a dust collector, and more particularly to a baffle for a chip separator of a dust collector for a wood chip and dust collector.[0003]2. Description of the Related Art[0004]Wood working using power tools, such as table saws, planers and other work cutting, forming and shaping tools generates a substantial quantity of dust and wood chips. Various measures have been used to collect the wood dust and chips, particularly in wood working shops that include multiple wood working, cutting and forming machines. One such dust collecting apparatus is referred to as a single stage dust collector 10, an example of which is shown in FIG. 1. The so-called single stage dust collector is distinguished from two stage dust collectors that include a first cyclonic dust separator, the output of which is carried to a second air filter cartridge. In the single stage collector as shown, an inlet hose...

AI Technical Summary

Benefits of technology

[0007]The present invention of one embodiment provides a dust collector for a wood working device that baffles the air flow between the dust and chip collecting lower container and the air filter of a single stage dust collector. A decrease in the quantity of dust and chips being carried from the lower collecting container or reservoir to the upper air filter is provided, reducing loading and blockage of the air filter and requiring less frequent cleaning of the air filter element.

Problems solved by technology

Wood working using power tools, such as table saws, planers and other work cutting, forming and shaping tools generates a substantial quantity of dust and wood chips.

This upwardly carried dust and chips loads or even blocks the filter element 22 and reduces the capacity of the dust collector, causing relatively frequent cleaning and emptying for proper operation.

The filter material experiences heavy loading and becomes increasingly blocked even when additional wood chips and dust are not being drawn into the system.
